Item description:

Here's my save for "Enah's Pal" Trophy - Won 10 rounds against Enah in battle. Not tested so, please post here if any other trophies pop. Enah's Pal

Resign & load up in-game " File 2 " . Upon load, You'll be right in front of the star. Interact to get the battles going.
You'll be able to go 10 rounds easily with Team 1 due to most of the team having max stats. I went 14 rounds before getting bored.

Fight Tactics:

Abram - ATTACK
Bernard - Skill > HEXA ARROW ( Enah will go down )
Titus - GUARD
Bastian - GUARD
( you'll have a small break before the pentagram spits another Enah out, so just use items or whatever to fill HP/MP to end the round )

Rinse and repeat

(IMPORTANT NOTE: The trophy does not pop immediately after 10 rounds. You need to lose the battle for it to pop. you will need to have all three parties knocked out. This will end the battle, and Enah will give your results. Do NOT quit out to the main menu, opt to start again, or use DRP to revive after defeating Enah 10 times!)
HP is maxed, so you'll need to just use up any skills that use up HP and let Enah do her thing.
